UBIFS assert failed in ubifs_set_page_dirty at 1421

[Caizhiyong]

Hi Artem,

We encountered a “UBIFS assert failed in ubifs_set_page_dirty at 1421 (pid 543)” problem when running MONKEY test in android platform.

It looks like this question : http://lists.infradead.org/pipermail/linux-mtd/2014-April/053523.html . 
And I tried the patch provided by hujianyang at huawei.com on that web page, but it couldn’t fix this problem.
We need your help, pls give us a hand, thanks.

Here is part of the log, linux version 3.10:
